- Description: This thesis investigates the impact on women of aggressive, demeaning and blaming talk in the online video game* space. The objective is to understand how players talk to each other and how this kind of talk presents issues for women trying to enter the online gaming sphere and become recognised as players. The main method was participatory observation and interviews with women who have experienced such talk. Key results which came from this research is that the process of keeping specific people out of communities through different means of talk - gatekeeping, women being viewed as objects of sexual gratification for men through bad representation in video games and media and using women as scapegoats for frustration and blame in the competitive online video game space, are the main issues which arise from the way players communicate with each other. In conclusion, the research presented that there needs to be an effective system of unlearning and relearning these behaviours in communities and a change in the way women are represented and seen in media is necessary in order to change the behavioural patterns which exist in gaming culture. , Thesis (MA) -- Faculty of Humanities, Journalism and Media Studies, 2022

- Description: In an attempt to control the harmful invasive alien plant, Opuntia megapotamica Arechav. (Cactaceae), a population of the cochineal insect Dactylopius opuntiae Cockerell (Dactylopiidae) (known as the ‘engelmannii’ lineage) is being considered as a potential biological control agent. This lineage of cochineal and the already established ‘ficus’ and ‘stricta’ lineages of the same cochineal species will inevitably hybridise where they occur in sympatry, possibly influencing the efficacy of the lineages on their respective hosts. Laboratory studies were conducted to investigate the likely outcomes of hybridisation between the ‘engelmannii’ and ‘ficus’ lineages. Detailed hybridisation trials, during which individual insects were manipulated and crossed, were used to compare the host affinity of F₁ and F₂ hybrids between the ‘ficus’ and ‘engelmannii’ lineages with the host specificity of the two pure-bred lineages. Host affinity was determined by plotting the net rate of increase (R) of a cochineal population developing on one host plant species against R on the other host plant species. F₁ hybrids were less species-specific than the purebred lineages in both crosses. Thus, the first generation will most likely remain effective in controlling both plant species in the field. F₂ hybrids produced a mixture of purebred and hybrid genotypes, with a higher net rate of increase when compared to purebred nymphs on their alternative host. Biological control of both Opuntia ficus-indica (L.) Mill. (Cactaceae) and O. megapotamica in the Eastern Cape Province, where both invasive alien plant species occur together, could be enhanced by the less specific nature of the F₁ progeny, which developed equally well on both O. megapotamica and O. ficus-indica; but this benefit will be reduced by the loss of host specificity of F₂ progeny. The success of biological control would depend on whether the species-specific nymph encounters its target host, because the less specific nymphs will have little effect on controlling either weed. These findings indicate that only purebred D. opuntiae lineages should be released in monocultures of their targeted weed. Long-term consequences of hybridisation should be monitored in the field. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2022

- Description: Cylindropuntia pallida (Rose) F.M. Knuth (Cactaceae) is an invasive alien plant in South Africa indigenous in the southern U.S.A. and Mexico. Large infestations of this species can be found in the Kalahari and arid Karoo regions of South Africa, which is also present in Namibia. Because it is a very spiny cactus, dense infestations have a negative impact on agriculture and natural ecosystems. This cactus has become naturalised to the extent that eradication is impossible and the negative impacts are steadily increasing due to its increasing distribution and density. The cochineal insect, Dactylopius tomentosus Lamarck (Dactylopiidae), is native in Mexico and parts of North America, such as Texas, Arizona, and New Mexico in the U.S.A. This cochineal species is highly specialized and associated only with Cylindropuntia species, a group of cacti that are primarily restricted to the same areas. It has been introduced into Australia and South Africa as a biological control agent to control various invasive alien Cylindropuntia species. This cochineal species has several biotypes specific to certain Cylindropuntia species hosts. A biotype is a clade that cannot be differentiated morphologically from others but has different host ranges and impacts depending on the host plant species. Included amongst biotypes that have been released in South Africa are D. tomentosus ‘imbricata’ and D. tomentosus ‘cholla’ for the biological control of Cylindropuntia imbricata (Haw.) F.M. Knuth (Cactaceae) and Cylindropuntia fulgida (Engelmann) F.M. Knuth var. mamillata (Schott ex Engelmann) Backeb. (Cactaceae), respectively. These biotypes have resulted in both host plants being under substantial control in South Africa. The first part of this thesis evaluated which of the two D. tomentosus biotypes already in use in South Africa could be an effective biological control agent for C. pallida. This was done by assessing the fitness of the cochineals on the three cactus species and assessing the impact that each of the cochineals has on each of the target weed species. Should these biotypes prove ineffective, there is a third biotype, namely D. tomentosus ‘californica var. parkerii’, which researchers in Australia have worked on and have found to be suitably host-specific for release in Australia and suitably damaging to C. pallida in that country. Therefore, this new biotype could be released in South Africa if it is required. Sexually compatible biological control agents, especially those closely related and occurring in close spatial proximity to one another, may interbreed and the impacts of this hybridisation are difficult to predict. It is important to understand the outcomes of the hybridisation of cochineal because it can affect the impact of the biological control agents and thus the control of the target weed. The second part of this thesis investigated the impacts of the hybridisation of the two cochineal biotypes by assessing the damage the agents would have on the target weed, and on C. imbricata and C. fulgida var. mamillata, in the presence of one or both cochineal biotypes. The ‘cholla’ biotype performed better on C. pallida than the ‘imbricata’ biotype, but neither biotype could control C. pallida to an extent similar to the control they provide for their respective target weeds, C. imbricata and C. fulgida var. mamillata. Both the ‘cholla’ biotype and hybrids of the two biotypes of cochineal were effective at killing C. pallida when both C. imbricata and C. fulgida var. mamillata were also present. This suggests that the ‘cholla’ or hybrids may be effective at controlling C. pallida when either C. imbricata or C. fulgida var. mamillata are also present in the field due to the high population density of cochineal that results under these circumstances. There are, however, many C. pallida infestations in South Africa where the plant is problematic and is isolated from other Cylindropuntia species, and these populations are unlikely to be controlled by the ‘cholla’ biotype or the hybrids. Neither of the cochineal biotypes that are used for biological control in South Africa are suitably damaging to C. pallida to warrant their use as biological control agents for this species. Dactylopius tomentosus ‘californica var. parkerii’ is therefore recommended for release based on its host-specificity and impact to C. pallida in Australia. , Thesis (PhD) -- Faculty of Science, Zoology and Entomology, 2022

- Description: This thesis centres itself around an investigation into the representations of the relationship between intimacies and ideas of romance, love, desire, and vulnerability in male relationships. The premise for this body of work was sparked by my own observations on the conflation of sex and intimacy in representations of queer male love—particularly (but not exclusively) in mainstream film and media. Whilst intimacy and sex are not unrelated, the over-emphasis on the physical when trying to represent the connection between two men led me to consider other ways in which a relationship or special connection could be gestured towards — through other kinds of signifiers that last longer than physical contact and point to the importance of a particular connection. In the introduction, I consider my own experiences as a closeted queer teen when contemplating representations of queer relationships in mainstream media. I explore several studies by gender and film theorists who consider reasons and modes in which the representations of queer intimacies on-screen are distorted to favour a presumed heterosexual audience. In the first chapter, I discuss two potential means by which to relay a more complex emotional state via the use of narrative signifiers. I examine T.S. Eliot's (1919) theory on the objective correlative in narratives as a means to explore the emotional state of a character through metaphors which open up the reading rather than illustrating it through dialogue or direct speech. I then explore Susan Stewart's (1992) ideas on souvenirs of personal experience. In Chapter Two, I conduct a close reading of three mainstream films, which employ such signifiers in the attempt to share more complex representations of queer male intimacies through well-developed storylines and characters. The films Brokeback Mountain (2006), Moonlight (2016), and Call Me by Your Name (2017) have been selected based on their use of the objective correlative and souvenirs as plot devices (rather than exclusively physical intimacy) to demonstrate the emotional resonance between characters. The third and final chapter explores my own use of objective correlatives and souvenirs as symbolic, narrative devices in my practical body of work: an online garden of remembrance. My practical work focuses largely on the process of creation of these intimacy objects (the objective correlative or the souvenir) through an investigation into my own poetry, which details my experiences of intimacies with other men, specifically where vulnerability and secrecy played a large role. , Thesis (MFA) -- Faculty of Humanities, Fine Arts, 2022
